Perhaps, but unless you're someone like Steve Jobs you're not going to come out with a TOTALLY new idea that no one in the world hasn't done or thought of already. Even Disney ripped off Kimba to make Lion King. http://www.hemmy.net/2007/04/28/disney-lion-king-ripped-off-...

If someone is stealing your ideas and executing better than you, then maybe you need to find out what they are doing right, so your next game does just as well or better than the clones.
